Cpu Or Hard Drive Speed?, Trouble w/ Logic Options

[whickus]

I love using Logic, but I'm having trouble with it lately. When doing projects in 24bit/96KHz with about 3 audio tracks and 5 instrument tracks my Audio meter (on the Logic system performance gauge) goes into the red, but the CPU meter is at less than half. About half the time it'll actually overload and stop. Here's my setup:

Dual 867 G4, OS 10.3.5, 768MB ram, Logic Big Box 5.5, seperate 7200 rpm 40GB ATA/100 hard drive for audio files.

I know Logic Big Box (same as Logic Express) does not take advantage of dual processors, but it seems like a single 867 G4 should be able to handle more than 3 audio tracks and a couple instruments.

My question is: Is my problem the hard drive or CPU or something else? Just wondering if anyone has any suggestions.

Thanks for any help.

In OS X, every program use both processors. The management is system wide, not application wide as it was in OS 9 (a nasty DIY software solution, now it's well tailored and smooth).

I wonder if it's not the 96 Khz handling doing a capricioso.

Was it sluggish too in prior OS X version or only 10.3.5?

Also, have you disabled journaling on the drive hosting the files? If not, you SHOULD.
